I'm more sympathetic to Analyzer's position on the Tsundere. I have no issue with physical comedy generally, but I'm not high on its insertion into either romantic or domestic relationships, especially if the setting is otherwise serious. It doesn't necessarily harm my opinion of the character (as its only one aspect of the whole), unless its pervasive or petty. Inuyasha got cited above...I really disliked that aspect of Kagome's character the longer that series went on. I never understood the humor in Naruto getting decked for Sai calling Sakura a hag. It's such an extreme overreaction (I am aware thats by design) that I just can't laugh and it, unintentionally, make her look bad by suggesting she's overly sensitive about stupid stuff. That's not to say it never works, but most of the time, it's not very funny. It shouldn't taken straight to argue that someone is a domestic abuser, but pointing out its extensive or common use, to me, isn't much a defense.
As to the other point, I'm less convinced that others that Sakura would have been more likely to have prevented Naruto from turning into a work-a-holic. I think on the whole, she is more assertive and, thus, more likely, on the whole to reign in his more negative qualities. However, being Hokage was his dream and I think Naruto feels a strong sense of obligation to the village. Him giving himself to the village at the expense of himself and family isn't necessarily hard to believe. That said, it is hard to believe he would do so for the paperwork when he's always been a people person and man of actions. Would Sakura really try to reign (or been effective) given his strong sense of duty? Would she have felt guilty for doing so?
Additionally, shy individuals can be more assertive when in more private settings. Is Hinata now that she's older? The suggests as much with the "scary mom," but doesn't give much. I think Sakura would have spoken to Boruto in the same way (they won't trash Naruto to the children behind his back.) and gave the same reasons, but would have chewed Naruto in private. Hinata? It's not impossible to believe, but who knows. I think her shy nature means that its even more important to show this because its harder to assume for her.
And I think this is really the core problem, Boruto takes its characters for granted and assumed a ton of stuff it cannot or should not. It's so lazy on the details. People presume Hinata didn't stand up for her kids because it wasn't shown. Scary Mom is told to us, not shown to us. Does she always demurely defer to Naruto? Who knows.
I think Hinata may be getting short shrift on this, but I have no sympathy for the writers if that's the case. Their approach has left then vulnerable to this complaint.
Having graduated from undergrad and law school, I've had my fair share of these kinds of professors and have found all of them to be blowhards who teach for their own self-glorification. And given some of what you've explained to us here about how well NH was fleshed out in the Naruto manga and how it has zero retcons/plotholes, I think you might wanna get a refund on Mr. Winegardner's course curriculum and instead apply for a good internship somewhere that'll give you actual on-the-job experience as opposed to listening to some elitist nut who will actually give you a failing grade because he doesn't like your story. If J.K Rowling can go from living on the streets to being a billionaire as a result of writing Harry Potter, then one can go a long ways without listening to pompous blowhards like Mark Winegardner.
As a fellow law school graduate, I cannot overstate my cynicism when it comes to law school, (and the bar exam( but that has to do with the chasm of what and how they teach and the actual practice of lawyering. My school often said a good benefit of having a JD was you could hang your shingle out once your graduate. Yeah, only if you want to commit malpractice and be fielding bar complaints within your first 6 months. For all but the top tier in the class, there is almost no opportunity to learn about HOW to be a lawyer before you graduate. Within my first 6 months of practice I had tried 10+ cases to a jury. Did law school team me about cross-examination, witness-prep, how to conduct voir dire without looking incompetent? Nope.
That said, I don't think all (or even most) of my professors were like this, but I did have a few who were probably drunk on their own self-importance. My worst professor was in undergrad though. It was thinly veiled indoctrination disguised as a class. Needless to say, I withdrew within a week.
